Hey guys, lately my temp gauge has been weird. The last sender that was in, would read way hot, 3-4 marks past 210, then way cold, 3-4marks below 210. I though maybe the t-stat was sticking so I replaced that, but still did the same thing. I recently replaced both the sensor and sender for the gauge. Now, The gauge reads from that thick white bar below 210, all the way to 210, and back down again. It does this several times every mile. I replaced the t-stat with a 195*. Does anyone else's do this, or is the gauge going bad, cause it doesn't seem normal to me. Our 91 K5 blazer (with same engine) warms up, and temp gauge is like a rock, never moves. How do I check the gauge and/or fix it?
